SES 5 3D Horizontal & Directional Drilling Software (with Technical Geosteering and Fuzzy Logic Steering Guidance!) - about SE
SES icon
SES icon








SES is for geologists who are dissatisfied with drafting or gridding-tool methods of geosteering. SES is 3D technical geosteering software that makes wellbore stratigraphic tracking quick-n-easy, accurate, and easily shared. Unlike any other geosteering software, SES provides a complete suite of software features to handle all of your horizontal drilling needs.


SES is horizontal and directional well bore drilling software...from pre-spud well planning with geologic model data integration through landing and 3D technical geosteering / stratigraphic interpretation while drilling or post drilling. Includes the 3DStratBlock  technical geosteering method with Relative Stratigraphic Depth (RSD) signal mapping, traditional 3D/2D well planning, survey calcs, Technical Hole Deviation (THD) calcs, THD logs, steering guidance from patented Fuzzy Logic control technology, and advanced visual geosteering interpretation tools using LWD (gamma ray, resistivity, etc.) and other data.

SES has successfully downloaded directional survey data (MD/Inc/Azi) and downloaded/quantized logging data (e.g., real-time gamma ray, ROP, etc.) from the WITSML servers listed below. There are likely numerous other WITSML servers that are equally SES-compatible, due to the intent and purpose of WITSML standards.

SES is practical oil & gas drilling software with advanced yet easy-to-use tools to determine:

  • WHERE your horizontal wellbore is stratigraphically located, AND (if used while drilling)

  • HOW to steer through or to your payzone

Geologic earth models are great for horizontal well planning (and easily entered from grid data and viewed in SES), but, for real-time operations, constant and intelligent interpretation of virgin data is critical to maximize effective payzone penetration at minimal cost. Interpretation of the new data subsequently refines the geologic earth model.


SES Technical Geosteering provides an estimate of the payzone formation location in 3D space over the drilled horizontal wellbore. The location and frequency of faults may also be identified, which can have multiple impacts on future development and remediation activities.


SES exploits cutting-edge FRIENDLY database technology to produce an experience like no other, with respect to directional steering data management, visualization, navigation, monitoring, and geologic interpretation.


With Technical Hole Deviation (THD) Technology, SES provides unsurpassed mathematical incorporation of real-time directional well planning and surveying for most-informed directional steering monitoring and decision making.


The odds--of knowing where the payzone is, while drilling or post-drilling--are maximized with SES. SES is industry's most advanced fully integrated directional planning and execution 3D technical geosteering software available and the only software that operates with 3DStratBlocks and RSD (Relative Stratigraphic Depth) signal mapping, and THD Technology. It's also the only related software that eliminates distortion (from vertical section projection) by going 3D!


But, if you only need general 3D directional well planning and surveying capabilities without THD, grid data integration, technical geosteering, or steering guidance, it is totally FREE.

FDS is a database program designed to capture and store pertinent drilling information at the source, i.e., the rig. FDS was developed in 1998 and field-tested by professionals experienced in drilling operations, drilling engineering, and database development.


FDS comes with an instant free trial period of 30 days before FREE registration is required for continued use. Simply download and use it. If you like it, then register. However, FDS is no longer supported/developed.


The current (and only) version of FDS is 1.1.  (2003-11-17)
